When you are using unify which uses NS to decide on the inode number,
it can not happen so that two files have same inode number because
the NS will be on the same filesystem. How did you conclude that two
files got the same inode number?

Can you paste your spec files? Can you make sure that both glusterfs
and glusterfsd are of the same version?

Yes, selfhealing should take care of it.
